The handle portion is 3/4 wide. I did not crank on the set screw. I assume it is frozen from rust and will take your TLC to move it.
I don't know that it came off a fruit press or coffee grinder. Those are keywords to help in sellers finding my item. This handle is very solid with no cracks or breaks.
